A "Time Interval" refers to the duration between two specific points in time. It can be measured in various units, such as seconds, minutes, hours, or days. Time intervals are essential in many fields, including science, mathematics, and everyday life, as they help us understand the passage of time and schedule events. In mathematics, time intervals can be represented on a number line, showing the start and end points. For example, the interval between 2 PM and 3 PM is one hour. Understanding time intervals is crucial for planning activities, conducting experiments, and analyzing data.
